我在 heroku 上玩瓶子，想换一个更“生产”的 WSGI 服务器 gunicorn。这是我的设置：

import os
import bottle
from bottle import route, run, template, request, static_file, error

class StripPathMiddleware(object):
    def __init__(self, app):
        self.app = app
    def __call__(self, e, h):
        e['PATH_INFO'] = e['PATH_INFO'].rstrip('/')
        return self.app(e, h)

# ................................................................. #

@error(404)
def error404(error):
    return template('view/404.tpl')

app = bottle.app()
run(app=StripPathMiddleware(app), server='gunicorn', host='0.0.0.0', port=int(os.environ.get("PORT", 5000)), debug=True, workers=3)

这是我的Procfile：

web: gunicorn SimpleServer:app -w 3

我在 SimpleServer.py 应用程序中尝试了设置和不设置工作人员数量的Procfile 。

在本地机器上，只有在应用程序中我有workers=3并且我没有指定工人开始gunicorn时它才有效：

(bottleServ)caerus@Artem:~/bottleServ$ gunicorn SimpleServer:app

但是foreman start存在问题，无论我使用什么设置都可以：

任何想法，将不胜感激！)

您正在启动 gunicorn 来运行应用程序，然后使用Bottle 的“运行”来生成另一台服务器（至少在 Heroku 上）。您收到错误的原因是初始服务器占用端口 5000，而第二个服务器无法访问它。尝试运行你的瓶子应用程序（python SimpleServer.py）它应该创建服务器本身。此外，当您将“应用程序”传递给运行时，http 服务器会生成您的应用程序的另一个副本（它会生成另一个 gunicorn 服务器），所以只需将其删除。

run(server='gunicorn', host='0.0.0.0', port=int(os.environ.get("PORT", 5000)), debug=True, workers=X)

python SimpleServer.py

应该是你所需要的。
